A circle has a sector with area \dfrac{3}{2}\pi 2 3 ​ πstart fraction, 3, divided by, 2, end fraction, pi and central angle of \purple{60^\circ}60 ∘ start color #9d38bd, 60, degrees, end color #9d38bd. What is the area of the circle?

Respuesta :

Answer:

9pi

Step-by-step explanation:

The ratio between the sector's central angle \purple{\theta}θstart color #9d38bd, theta, end color #9d38bd and 360^\circ360  

360, degrees is equal to the ratio between the sector's area, \green{A_s}A
